Senior Software Engineer, Mobile (React Native)

About this role

# Hi! We're Forerunner.

We believe that climate adaptation is a necessity, not a luxury, and communities deserve access to powerful software that helps them plan for the future. The challenge of climate change is complex – it implicates how municipalities plan, manage capital, and communicate to both residents and higher levels of government. Forerunner helps local communities do these things better by empowering them to access, understand, and mobilize local-level flood risk data at scale.

## The Role

This is a high-impact role at the intersection of geospatial data, field operations, and climate resilience—where performance, reliability, and usability directly affect outcomes for communities.

## What You’ll Do

• **Build and scale mobile applications using React Native**, delivering high-quality, performant experiences across iOS and Android
• Own features **end-to-end**, from early design and architecture through production and iteration
• Develop **intuitive, responsive mobile interfaces** that work seamlessly in real-world field conditions (low connectivity, high urgency)
• Collaborate closely with product, design, and backend teams to ship impactful features
• Integrate and optimize **APIs, geospatial data, and real-time workflows** within mobile applications
• Identify and solve performance bottlenecks to ensure **native-like speed and reliability**
• Contribute to mobile architecture decisions, including when to leverage **native modules (iOS/Android)** for performance or platform-specific needs
• Improve developer experience through tooling, testing, and best practices
• Mentor engineers and help raise the bar for mobile engineering across the team
